The vulnerability identified as CVE-2006-4120 represents a critical cross-site scripting flaw within the Recipe module for Drupal versions 4.6 and earlier. This security weakness exists in the recipe.module component and affects all versions prior to 1.54, creating a significant risk for web applications utilizing Drupal content management systems. The vulnerability allows remote attackers to inject malicious web script or HTML code into web pages viewed by other users, potentially compromising the security of entire web applications.
The technical nature of this XSS vulnerability stems from inadequate input validation and output sanitization within the Recipe module's code implementation. Attackers can exploit this weakness through unspecified vectors that likely involve user-controllable input fields or parameters within the recipe module functionality. The vulnerability manifests when user-supplied data is directly rendered into web pages without proper sanitization, enabling attackers to execute malicious scripts in the context of other users' browsers. This type of vulnerability falls under the CWE-79 category of Cross-Site Scripting, specifically representing a weakness where untrusted data is improperly handled during web page generation.
The operational impact of this vulnerability extends beyond simple script injection, as it can lead to serious security consequences including session hijacking, credential theft, and unauthorized data manipulation. When exploited successfully, attackers can establish persistent malicious presence within affected web applications, potentially using the vulnerability to redirect users to malicious sites, steal cookies, or perform actions on behalf of authenticated users. The risk is particularly elevated in environments where the Recipe module handles user-generated content or where multiple users interact with the same web application, as the vulnerability can affect any user who views compromised content.
Organizations running affected Drupal installations should immediately implement mitigations including upgrading to version 1.54 or later of the Recipe module, which contains the necessary security patches to address this vulnerability. Additionally, administrators should consider implementing input validation mechanisms, output encoding for all user-supplied content, and regular security audits of third-party modules. The vulnerability demonstrates the importance of maintaining up-to-date content management system components and highlights the need for comprehensive security testing of web applications. Security professionals should also consider implementing web application firewalls and monitoring systems to detect potential exploitation attempts. This vulnerability serves as a reminder of the critical importance of keeping all web application components updated and following secure coding practices to prevent XSS attacks that can compromise entire web infrastructures.
